A Florida man who divorced his wife to marry the Spanish foreign exchange student they were hosting is accused — along with his new bride — of sexually assaulting the girl’s teen sister, police said.

Dale Leary and his wife hosted exchange student Marta San Jose, 16, when she moved to South Florida from Spain in 2012, local station WPLG reported.

Twenty days after she turned 18, Leary, 50, left his wife to marry San Jose, unbeknownst to the girl’s family, according to the station.

San Jose invited her then-14-year-old sister to move from Spain and live with the couple in 2014.

San Jose, who is now 21, manipulated her younger sister into thinking she had been sexually assaulted by their parents to convince her to allow Leary to perform a vaginal examination “to prove she was sexually assaulted,” according to arrest affidavits.

Miami-Dade police say Leary and San Jose had sex in front of the teen and that San Jose convinced her sister to allow Leary to perform sex acts on her, telling her it would help her deal with being a sex-abuse victim.
